Message from the IRS.  I have a canned message telling me to return the call as soon as possible.  They have an arrest warrant out for me on past due taxes.

Got a call from this number stating IRS that I need to call before federal court and get arrested. This is crap!!!!!

Yes it's crap and a scam.  The IRS will send you a letter or a certified letter and would give you the option to make things right with them before any legal proceedings take place.  You would have the option to, first, know what you have frauded them on and second the right to an attorney to defend your case.  You would also be notified that you have been audited and are being investigated for fraud.  Your assets and bank accounts would be frozen I am almost certain.

just got one too.  says I'll be arrested if I don't call back.  don't give any information

Phone screen displayed PRAVIN K and this number. Autotranscription of recorded message follows:

"Case filed against your name. This is officer Breanna Scott from the Department of United State treasury. This call is official final notice from United State treasury. The nature and purpose of this call is to inform you that we have received a legal petition notice concerning a tax fraud against you. Still before the matter goes to federal claims court house or before you gets arrested. Please call immediately on our hotline division number that is 631-685-0460. Make sure you call us as soon as possible."

A transparent scam.
